Abstract: 205,532. Marriott, R. H. June 13, 1922. India-rubber &c. threads.-India-rubber &c. is extruded to form filaments which are associated into threads to form artificial silk. The rubber may be in the form of solution, latex, masticated dough, or a vulcanized gel. The rubber when not in gel form, is preferably vulcanized contemporaneously with or subsequently to the formation of the artificial silk. In the case of solutions and latex, the filaments may be extruded into a precipitating or coagulating bath or into heated air, steam &c. and through a bath containing for example shellac and alcohol, or soap and water. to remove tackiness. Vulcanization may be effected by adding vulcanizing ingredients to the dough, solution &c. and extruding under conditions which effect vulcanization, or the rubber may be treated with one vulcanizing component prior to extrusion, and with another subsequently, or the filaments may be led through a bath or atmosphere containing sulphur monochloride. To reduce extensibility, substances such as gutta percha, balata, or vulcanized oil may be added to the solution or dough which may also be dyed. A suitable solution is one containing 7-20 per cent of rubber.

Abstract: 1309700 Speech recognition LISTENING Inc 8 April 1970 [26 May 1969] 16569/70 Heading G4R Apparatus for determining whether a given signal corresponds to a preselected vocal sound, provides a plurality of differently delayed signals from the given signal and mixes a proportion of each to obtain a composite signal, an output signal being generated when the average amplitude of the composite signal crosses a threshold. The speech signal is supplied via an automatic-gain-control amplifier to a tapped delay line which feeds a correlation network using variable gain amplifiers for the weighting (gains between plus and minus 2) and resistors. The outputs of the network (corresponding to possible phonemes and/or speakers) go to respective detectors which determine the average amplitude of each. The smallest (or largest) of these averages is determined by a comparator to identify the phoneme/speaker. The comparator is disabled if the original speech signal does not exceed a threshold. The circuitry above can be simulated on a digital computer.
